How about an allocation exit that abends or flushes the job after the 10th tape drive is allocated unless the job is in class Q. Then make the Q initiator available 0300-0400 on alternate odd-numbered Sundays. No one should be allowed to consume resources they don't need out of laziness, especially when it causes other problems.
However, if you must accommodate the diva, JES2 exit 6 can alter the encoded JCL. We use it to update the parameters of an OUTPUT statement so users are not affected by a printer replacement. This included changing the length of some parameters. It should work for DD cards also. :>: -----Original Message----- :>: From: IBM Mainframe Discussion List [mailto:[email protected]] On :>: Behalf Of Mike Schwab :>: Sent: Friday, October 25, 2013 1:55 PM :>: To: [email protected] :>: Subject: Is it possible to write an exit to add DEFER to a VTAPE :>: allocation? :>: :>: We have some job steps that use ICETOOL to copy 50 DASD or VTAPE :>: datasets to two VTAPE datasets.
